In this model, decentralized independent node operators continuously aggregate and push data updates to the blockchain when specific price thresholds or heartbeat intervals are reached. This approach enhances blockchain scalability, supports a broader range of data products, and ensures timely updates. ### Trusted Data for DeFi APRO Data **Push** **Model** is widely utilized in various applications, especially in DeFi protocols and smart contracts, providing highly trusted, real-time, and secure data. It is also critical for emerging markets like Bitcoin Layer 2, addressing the growing demand for precise data in blockchain applications. ### Reliable Data Transmission The APRO Data Push model employs multiple high-quality data transmission methods, leveraging a hybrid node architecture, multi-centralized communication networks, the TVWAP price discovery mechanism, and a self-managed multi-signature framework. This ensures the delivery of accurate, tamper-resistant data, safeguarded against vulnerabilities or oracle-based attacks, ensuring reliability across diverse use cases. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.apro.com/en/data-service/data-serivce/data-push.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
